This paper describes an automatic manipulation system by motion controlled water flea. The authors have examined the motion control of various protists by using their taxis and tried to use them as a living micromachine. However, there are not only these unicellular microorganism but also various multicellular organisms such as small Crustacea like water flea, etc. Multicellular microorganisms also have their taxis. Therefore, it may be possible to apply their taxis to control their motion like protists. Therefore, in this study, the motion control method of Daphnia magna was investigated by using their phototaxis. The results showed that Daphnia shows strong positive phototaxis to the blue light. A dish-shaped motion control pool was produced. Blue LEDs are installed in the virtical wall of the pool. Manual motion control experiments were done in this pool by changing the turned on LED by joy stick operation. The results showed that Daphnia has much better controllability and maneuvability than protists such as Paramecium or Euglena.
